...about the visual program
This visual program demonstrates the use of data-driven scalar
and integer interactors. The integer interactor controls the
slab position and is constrained by the size of the data sets.
The Scalar interactor which chooses the isosurface value is also
data-driven, so that it cannot exceed the range of the data values.
...about the conversion to web page
The original visual program rendered an object and used the Collect
tool to combine that with a color bar and a caption. The web version
of the .net file, does not use Collect. Instead each part of the
original image is separated into its own Image tool. The resulting
pictures are then assembled in an html table giving the web page
author greater flexibilty in layouting out the document and increasing
the proportion of meaningful gif byte transmitted with each new image.
